In the pdf there is the "binary" marker on the line after the pdf

It's on purpose.

At least PDF A-1 (ISO 19005-1:2005(E)) requires these binary markers.

"6.1.2 File header
The % character of the file header shall occur at byte offset 0 of the file.

The file header line shall be immediately followed by a comment consisting of a 
% character followed by at
least four characters, each of whose encoded byte values shall have a decimal value 
greater than 127."
ok, i'll add a suitable blob then ... (i don't have these iso standards as i'm not going to spend money on iso standards)
